SPECIFICATION forming part of Letters lPatel-1t No. 729,333, dated May26, 1903. Application led Julyy 30, 1902. Serial No. 117,646. l (Nomodel.)

To all whom t may concern:

Be it known that we, ABRAHAM .IIAAS and EDGAR BARUCH, citizens of theUnited States,

and residents of San Francisco, in the county of San Francisco and Stateof California, have invented a new and Improved RawLIVool- \VashingApparatus, of which the following is a full, clear, and exactdescription;

The invention relates to apparatusl for washing raw sheeps wool andsimilar ibers,

and its object is to provide a new and im!y proved raw-wool-washingapparatus which is simple and durable in construction, very effective inoperation, easily manipulated, and arranged to permit its use in localwool-grow-- ing centers, to allow of washing' or cleansing raw sheepswool andl other textile iibers With- A practical embodiment of theinvention isv represented in the accompanying drawings,

forming a part of this specification, in whiclr similar characters ofreference indicate corresponding parts in both views.

Figure l is a front elevation of the improve-, ment, parts beingshown'in section; and Fig.

2 is a side elevation of the same. Y

The improved apparatus is'inounte'd-on a suitably-constructed frame A,which supports an extractor B, preferably in the form of a cylinderclosed atthe lower end and provided at its upper end with a removablecover B for introducing or removinga wire cage C, containing the rawsheeps woollor like liber Dtobetreated, i; .I The upper end of theextractor B is connected by a pipe F,`having a valve E', with the lowerend of a reservoir F,for containing benzin or a similar hydrocarboncleansing compound for dissolving the fats andV greases contained in theraw sheeps wool yheld inthe cage C,"inserted in the extractor B. Thebottom of the latter is connected by a pipe G, having a valve G, with acaldron I-I, in the shape of a closed vessel, containing in its bottom asteam heating-coil I, having one outer end I provided with a valve I2and connected vwitha steam-supply pipe J, leading from a boiler yorsimilar source of steam-supply. A branch steam-pipe K leads from thesupplypipe .I into the lower end of the extractor B, land the said steambranch pipe K is provided with avalve K', normally in a closed position.

From the top of the caldron H leads a pipe L, connected at its upper endwith a condenser Nin the shape of a plurality of coils extending withina water-tank O, through which passes water or other cooling mediumsupplied by a pipe O and carried off by a discharge-pipe O2. The lowerend of the condenser N terminates in a pipe N', connected with the upperend of the reservoir F,

whichlatter is provided at its bottom with a gage F' for determining thepresence of water of condensation, as hereinafter more fully described,and ythe said reservoir F is also provided with a gage-glass F2 forindicating itheplevel of the liquid contained in the reser- .with thepipe L, leading to the condenser N.

The caldron H is provided with a chargingfunnel Q, having a valve Q.

rlfhe operation is as follows: The raw' sheeps wool or similar ber isplaced into the cage C, and then the latter, with the wool, is

introduced into the extractor B, after which lthe cover B/ thereof isclosed and the valve 'E/ ris then opened to allow the benzin to iiow byits own gravity from the overhead reserv-voir F through the pipe E intothe extractor B in contact with the wool, so as to dissolve fats andgreases adhering to the wool fibers and at the same time loosen dirt andother impurities. The liquid benzin percolates through the wool andfinally passes through vthe pipe G into the caldron II, carrying with itthe dissolved fats and greases as well as other impurities.

In the caldron I-I the benzin is separated from the fats, greases, dirt,and. other extraneous matter by heat emanating from the coil I, whichheat evaporates the benzin, and the vapors now pass from the caldron I-Iup through the pipe L into the condenser N, in

IOO

which the benzin vapors are converted back into liquid form, passing bythe pipe N' into the reservoir F to be reused in the extractor B, in themanner above described. This operation is continued until the greasesand fats of the wool have been completely dissolved and removed from theextractor.

As shown in the drawings, the ealdron Il is located below the extractorB, so that the liquid benzin and the substances dissolved therein flowby gravity from the extractor into the caldron whenever the valve G isopened. If desired, the valve G may be closed and the liquid benzincontaining the dissolved fats and greases may be siphoned from theextractor ll, and ii'or this purpose a self-starting siphon G2 isprovided, connected at its short leg with the pipe G and at its long legwith the ealdron ll, the said long leg having a valve G, which may bcclosed whenever desired.

The pipe G is provided with a test-cock l to indicate the condition ofthe benzin and the substances dissolved thereinthat is, when the benzinshows comparatively clear at the test-cock, then the fais and greaseshave been removed from the wool and carried to the caldron ll. 'hen thishas been done, then the valves l2, G, G, and E are closed and the valveK in the pipe K and the valve P in the pipe P are now opened, so thatsteam passes from the supply-pipe .l through the pipe K into the lowerend of the extractor B and through the wool contained therein, so thatany benzin adhering to the wool, cage C, or wall of the extractor l5 isvaporized and carried with the steam by way of the pipes P and L to thecondenser N to be condensed therein. The water of condensation flowingby the pipe N into the reservoir F readily separates from the benzin,and this water can now be drawn o through the gage-cock F, which alsoindicates when the water has been completely Withdrawn from thereservoir and the latter only contains benzin. Then the benzin has been.expelled from the extractor B, as described, then the valves K and P areclosed and the cover B is then opened and the cage C, with the cleansedwool, is removed, and the cage is refilled with raw clipped wool andagain inserted in the extractor B. The above-described operation is thenrepeated-that is, the valves E', G, and I2 are opened to subject thewool in the extractor to the action of the liquid benzin to allow thebenzin and the fats and greases dissolved by it to pass to the caldronll, in which the benzin is vapor-ized and separated from the fats andgreases and other extraneous matter, as above explained.

The bottom of the caldron H is provided with a discharge-faucet H fordischarging the fats, oils, and other impurities from the caldron IIwhenever it is desired to do so.

From the foregoing it will be seen that the benzin employed is used overand over again, so as to permit of cleansing the wool at a comparativelylow cost.

Having thus described our invention, we claim as new and desire tosecure by Letters Patentl. In an apparatus of the class described, thecombination of a main frame, an extraetor mounted centrally thereof, acage for containin the material to be treated and adapted to be insertedin said extractor, a reservoir situated above said extractor andconnected therewith, said reservoir supplying benzin to the extractor, acaldron below said extractor, means for siphoning the benzin from theextractor to the caldron, a heating-coil in said caldron, a condenserabove the reservoir communicating with the caldron and said reservoir,and means for introducing a charge of steam upward through the materialin the extractor, as set forth.

2. In an apparatus of the class described, the combination of a mainframe, an extractor provided With a cage for the material, mountedcentrally of said frame, a reservoir for a liquid cleansing compoundmounted above and connected with said extractor, a caldron provided witha heating-coil mounted beneath the extractor, a pipe leading from thebottom of said extractor, a self-starting siphon having a short legconnected with said pipe and its long leg with the caldron, a valve forsaid siphon, a reservoir mounted above the extractor, a condenser abovethe reservoir, said condenser communicating with the caldron ,the vaporpassing from the caldron being liqueiied in the condenser, means fordrawing off the water from the condenser, and means for conveying theliquid cleansing compound from the condenser to the reservoir,substantially as set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
